vision of an improved tank of this character y provided with means for readily filling and emptying the tank to prolong the life of the bottom of the tank.

A further object of the invention is the provision of an acid tank for removing scales from bundles ofv iron rods having an improved construction of brace supports for the member carrying the rods and having improved reinforcing portions for the ,rod support to prevent wearing of the ends of the support.

To attain they above and other objects which will be apparent from the following description I have provided an acid tank and rod support substantially as hereinafter described and as illustrated in the accompanying drawing, but it will be understood that I may make any changes in the specific construction shown within the scope of the claims without ,departing from or exceeding the spirit of the invention.

Figure l represents a side elevation of my improved tank. Fig. 2 represents a top plan view thereof. Fig. 3 represents a 'longitudinal sectional View with the rod supporting beam in position. Fig, 4C represents a cross sectional view thereof. Fig. 5 represents a sectional view of the end of the beam and cap plate, and Fig. 6 represents a plan view of the spraying belt-with the beam resting thereon.

In the drawings, the numeral 1 designates the planks forming the bottom of my tank, having rising therefrom the side forming planks 2 and the end planks 3, there being a plurality of bolt rods 4 passing vertically through the middle of the various `planks to secure them together, the planks thus being disposed on each side of the bolt rods to pro tect the rods from the eating action of the acid contained in the tank, while at the same time the position of said rods prevents warping or displacement of the planks. To brace kthe bottom I secure therebelow the transversely extending wooden beams 5 through which certain of the bolt rods 4 pass,trans versely extending bolt rods 6 passing through the sides and end planks to secure them in desired position.

` To facilitate the filling or emptying of the rectangular wooden receptacle thus formed, in place of forming merely a plugged opening in the bottom to drain the same, as is now the common practice, which opening rapidly becomes enlarged and soon impairs the usefulness of the bottom, I have prof yided an improved iilling and emptying pipe. Projecting upward through the bottom planks 1 and dushed with the upper 'face thereof is the pipe 7 having the locking washers 8 engaging the upper and lower faces of the bottom plank to provide a tight joint, while secured to the lower end of the pipe is the elbow 9 into which is screwed the horizontally extending pipe 10 having connected to its outer end exterior to the tank the elbow 11 retained b the pivotal coupling 12 which permits'the el ow to swing aroun on the pipe 10, a pipe 13 of length greater thanthe height of the tank being secured to the free end of the elbow 11. To fill the tank and prevent the dangerous splashing of the acid lcaused by directlypouring the acid into the tank, I place the pipe 13 in vertical or substantially vertical position and secure it there by the locking member 14 projecting from the side of the tank, and4 I then pour the acid into the yupper end of said pipegthe acid flowing down and through the connected pipes and up into the interior of the tank to thoroughly engage the rods suspended in the tank. To empty the tank the pipe 13 is swung on the pivot connection 1f? until its end is lower than the ipelO, when the acidvwill flow from the tank through'the' various pipes and be discharged from the" pipe 13.

To support the rods to be treated withinthevtank and prevent the lower ends of the supporting members from being quickly driven through the bottom of the tank as frequently occurs wit-h'the type of support at present in general use, I secure at the bottom of the tank near each end the trans versely extending beam 15 having ends Inaking mortise and tenon engagement with the sides of the tank, while rising centrally from the beam 15 is the post 16 havingits v end engaged respectively in the beam 15 and in the transverse beam 17 disposed intermediate the height of the tank and vhaving its ends mortised in the sides of the tank to further brace the same. Resting upon and slightly inlaidin thel beam 17 is the horizontal portion 18 of the' L-shaped plate 19 which extends upward to the upper edge of t-he tank and has the outwardly and downwardly bent end 20 fitting over the upper edge of the end of the tank to both protect the end of the tank and support the portion 18 of the plate.

Secured to the vtank at one side of the plate 19 is the guidevmember 21 having the upper inclined end 22 and having its lower end mortised in the beam 17 In the useof the' tank, I suitably lower the stem beam 23 bearing the bundles of rods 24 into the tank, the ends of said beam being guided into position by the guide member 21, while the plate 19 engages the ends'of the beam to prevent the same from rubbing against the readily'worn vplanks 3 and the Vplate end 18 reinforces the beam 17 andl aids in,

supporting the stem beam 23.

To prevent the ends of the stem beam 23 from rapidly wearing, I mount thereon the loosely ttingrectangular collars 25 having the upwardly projecting lugs 26 formed with the aperture 27 to receive the lifting hook of a crane. These collars 25 are further useful to protect the ends of the beam when the same is yplaced upon the chains 28 of the spray belt,'the collars 25 resting on ythe chains while t-he stem, beam and rods 24C hang between the chains 28 where the rods will be struck by the cleansj ing spray.

From the foregoing description taken -in connection with the drawings, the construction of my improved acid tank will be readilyunderstood, and it will be seen that I have provided 'a tank of extremely simple and durable construction in which the securing rods are set in the beams and thus protected from the action of the acid Whilev so bracing and securing the parts of the tank together as to securely brace the side andother parts of the tank, while pre venting the warping thereof. It will further be seen that I have obviated the danger of the acid splashing and also prolonged the life of the bottom of the tank by providing an :open pipe atthe bottom thereof having an end adapted for use in one position for lling the tank and in another position as a..discharge pipe for the tank, while to protect the bottom from t-he wearing action of the stem supporting posts, I have provided an improved construction of reinforced rod supports and have further provided an improved combination reinforcing collar and lifting eye'for the ends of the stem'beam which may be quickly applied thereto.

The advantages of my improved acid tank and rod supporting stem will be fully apparent from the foregoing description taken in connection with the drawings, and it will be seen that I have .provided a simple and efficient acid tank of thoroughly practical and economical construction which will commend itself to all those familiar with the construction of ordinary acid `tanks as being a great improvement thereover.

I claim:

1. An acid tank, comprising a wooden re ceptacle, ar transverse bracing beam secured to the bottom of the receptacleat each end,

*verse beam, a transverse beam mounted on the support and having its endsl mortised 1nl the sides of the tank, a, bracing plate eX- tending over the upper edge of the end of the tank and having a depending L-shaped arm extending down the side of the tank and resting on the upper transverse'beam, and a guide'member secured at theside of the plate to the end of the tank and resting on` the beam adjacent the plate, said guide having an outwardly tapering upper end.

2. An acid tank, comprising a wooden receptacle, metal bolt rods passing through adjacent sections of the receptacle and hav-` ing their body portions entirely inclosed by the wood of said sections, a combined inlet and discharge pipe for the tank, an interior lbracing structure formed on and rising from the bottom of the tank, said structure com'- prising a pair of transverse beams 'and a support `connecting the same, a reinforcing plate inlaid in the upper beam and extending upward and over the edge of the end of the receptacle, guides adjacent said plates, and a longitudinally extending supporting beam mounted on the inlaid plate and having reinforcing metal members resting on the plate and provided with upwardly projecting eyes to receiveu a lifting device.

In testimony whereof I aiix my signature,

`in the presence of two witnesses.
